IMPROVED MACHINE FOR FINISHING LEATHER.

Specification forming part of Letters Patent No. 40,735, dated December 1, 1863.

To all whom it may concern:

Ba it known that I, SEWARD I. Conn, a resident of South Danvers, in the county of Essex and State of ll'litSStlCllliSGtf-S, have in vented an Improved Machine for Diciug, Poldeclare the same to be fully described in the following specification, and represented in the accompanying drawings, of which Figure l is a side elevation, Fig. 2 a front elevation, and Fig. 3 a vertical section, of such machine. 1 I

The nature of my invention c nsists as follows: First, in a peculiar mech sm for obtaining the compound movement of the vibrator or dicing-statt': also,in the combination mechanism with the dicer or finishing-tool and its-staff or vibrator; also, in the combination and arrangement of an adjustable. smoothing-tool with the dicer and its staff; also, in the combination and arrangemel'it of a (liccr-cleansing mechanism with the timer, its stafl', and curved btd.

In the drawings,'A exhibits a table, from and above which a frame, 13, extcnds,'and serves to support the fulcrum s of a rockerlever, U, which is arranged as shown in the drawings. The dicing-staff or vibrator 1) is jointed to one arm of the said rocker-lever, and at its lower' end supports the slicker, dicer, or finishing-tool a, which is fastened to a tilting plate or frame, 0, hinged to the lower end of the vibrator or dicing-staff D. A forked connecting-rod straddles the vibrator, and isjointed-io it and to the crank-pin ofa flywheel, E. Furthermore, there is jointed to the connecting-rod, within its fork and ata short distance from the dicer-stafi', a pitman, e, which extends upward and at or near its upper end is jointed to the rocker-lever (J, hereinbefore described, the arrangement of the said pitman with respect to the dicing-staff androcker-lever being as shown in Figs. 1 and'3.

On revolvingthe fly-wheel in the direction of the arrow 1 marked thereon, the dicer-staft' will not only be vibrated with a pendnlous motion, but while moving toward the fly-wheel the said dicing-staff will be moved or pressed downward toward the bed in inanner'to keep the dicing or finishing tool in contact with a piece of leather when on the bed. So, while moving away from the bed thedicing-stiafi I will be raised upward so as to elevate the dicer or polishing-tool entirely off and keep it out of contact with the leather.

In advance of the polisher or dicing-tool there is arranged a brush, H, held by a suitable supporting-frame, (I, having one or more springs, 0, so arranged and applied to it and the dicer-statt' as to press the brush in a down? ward direction and upon the leather while such leather may be resting on the bed G. This brush moves with the dicer and its staff, and is for the purpose of removing from the surface of the leather, and iii-advance of the dicer, any dirt, grit, or any extraneous matter that may collect on the leatherand be likely surface from the action,

to cause injury to its ot' the dicer. There is also placed to the rear of the dieer a smoothing-tool, I, it being car-j ried by a clamp, f, attached to the dicer-stafi".

A spring, g, suitably applied to thesmooth- 3 ing-tool, serves to depress it, as occasion may require. The object of the smoothing-tool is, remove-from the surface of the leather, while the machine may be at won k, more or less of the graining made by thejdicing-tool, or, in other words, to tone down the desirable. The said smoothing-tool may also be employed irrespective of the dicing-tool,

and either one orboth maybe used, as occasion may require. A rod,-i, jointed to the tilting plate b of the dicingtool, extends upward along the dicer-statf, the said rod at its upperend being jointed to the shorter arm of a lever, k, whose-fulcrum l is supported by the dic'erstaif. This lever projects from thedicer-stafl',

and has projecting from its longer arm a pin or stud which goes between the prongs of a forked lev'e'ig m, formed and arrangedas shown in the drawings. By layin ghold of the longer arm of said forked lever and moving the same the cheer-tilting frame may be either raised or lowered, as circumstances may require.

At the front end of the curved bed G there is-arranged a dicer cleaning tool or scraper, o, whichis supported by which vibrating movements may beimparted by me'ansot'a foot-lever, q, and a'c'onnectionrod, r, the same being arranged as shown in -Fig's. l and 3. B y elevating the scraper pre; vious to the expiration of any advance movement of the 'dicer; the said dicer, in the contin-nation of its movement, will be carried in contact with the scraperin such manner as to graining as may be a vibratory'lever, p, to Y be cleaned or scraped thereby. In this way the grease or dirt which may collect on the dicer or polishingtool may .be removed therefrom.

I claim 1 The peculiar mechanism for obtainjn g the compound movement of the dicing-staff l), the same, consisting of the fly-wheel E, the connesting-rod F, the rocker-lever (J, and pitman c,ar1"anged and so as to operate substantially as hereinbefore specified. v

2. The combination and arrangement of the brush H or leather-cleaning mechanism with the dicer a and its stafit' D.

3. The combinationand arrangement of the adjustable smoothing-tool I with the dicer a audits staff.

4; Thenqombination and arrangement of the scraper 0' or cleaning mechanism with the dicera and its curvedbed G. r
